Overview of FDA Drug Approval and Labeling.

Area of Science:

• Regulatory Science
• Pharmaceutical Science
• Public Health Policy

Background:

• The U.S. Food and Drug Administration (FDA) regulates medical products, food, and tobacco.
• Historical lack of public protection regarding food and pharmaceutical contents and sales.
• Evolution of legislation ensuring rigorous review of drugs and biologics for safety and efficacy.

Purpose of the Study:

• To highlight the importance of FDA-approved drug labeling for safe and effective medication use.
• To emphasize the critical role of prescribing information for healthcare providers.
• To address the implications of off-label drug use in clinical practice.

Main Methods:

• Review of FDA regulatory history and legislative amendments.
• Analysis of the function and importance of FDA-approved drug labeling.
• Discussion of the context and risks associated with off-label drug prescribing.

Main Results:

• FDA regulation ensures marketed products are safe and effective for intended use.
• FDA-approved drug labeling is the primary communication tool for safe and effective drug use.
• Off-label prescribing involves unapproved uses not subject to rigorous FDA benefit-risk assessment.

Conclusions:

• Healthcare providers must be familiar with FDA drug labeling for informed prescribing decisions.
• Understanding prescribing information is vital, particularly for new drug introductions.
• Off-label drug use requires careful consideration due to lack of FDA evaluation for those specific contexts.
